Project Detail
| Objective on the basis of need | The project aims to recast polymeric waste into functional nanoparticles of tuneable anisometry which will be repurposed via field induced assembly into flakes that exhibit vibrant structural coloration as sustainable alternatives for conventional pigments in paints. |
| Executive summary of the proposed project (In 250 words) | Conventional paint pigments are ecologically toxic, specifically for marine ecology. Structural colour from assembled microparticles arises simply from material microstructure and its interaction with incident ambient light and requires no chemical intervention. Thereby, structural color flakes offer a sustainable alternative to pigments for formulating paints. In this study, we will harvest the microparticles from polymeric waste where, the polymers will be recast into microparticles of tunable size and shape via methods of precipitation. The microparticle raw-material will be assembled into flakes that exhibit brilliant color due to their ordered microstructure. The assembly itself will be conducted through conventional mechanical and electrical force fields which do not require any extensive technology. Once assembled, the microparticle assembly will be milled to produce these flakes. The flakes can then be used to replace the chemical pigment for use in dyes, paints and coatings. When such paints wear away, they can again be repricipated into particles and routed back into the production chain using the method mentioned above. Moreover, repurposing polymeric waste into the microparticles establishes a circularity in the process, as mandated by the UN SDGs. |
